Application filed April 16, 1897.

T0 @ZZ whom t 17mg concern:

Beit known that I, JOHN H. GILMAN, a citizen of the United States, residing at Ottawa, in' the county of La Salle and State of Illinois, have invented a certain new and useful Improvement in Corn-Sheller Attachments, which is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure lis a general side elevationof a cornsheller constructed according to my invention. Fig. 2 is a plan view of a portion thereof with parts broken away. Fig. 3 is a horizontal section on the line 3 3 of Fig. l. Fig. el is a view in elevation of the lower end of the elevator looked at from the inner side. Fig. 5 is a detail View of the upper mounting of the elevator. Fig. G is an end elevation of the parts shown in Fig. 5. Fig. 7 is a vertical cross-section on the line 7 7 of Fig. 5. Fig. S is a horizontal section on the line 8 8 of Fig. l.

My invention relates to corn-shellers, and particularly to that mechanism adapted to elevate the shelled corn from the lower portion of the machine and transfer it to whatever receptacles may be provided.

My invention has for its principal object so to mount the elevator as to enable it to be swung from its operative position into one more suitable for the machine when the same is to be conveyed from place to place; and it consists in means adapted to this end,together with other devices and features of construction connected with the elevater.

Referring to the drawings by letter, A A designate the main sills of the framework of a corn-Sheller carried by the axles and wheels A'.

A2 designates the front and A3 the rear main frame-upright, adapted to support the body of the machine, of which A4 represents the upper casing of the shelling-cylinder.

Between the two frame-uprights A2 and A3 and somewhat nearer the latter there is secured to the two sills A a transverse beam' A5, which extends outward upon one side of the sills and machine, as particularly shown in Fig. 3. Its purpose will be later described.

The elevator B comprises a casing B', which is inclosed at its lower end except upon that side adjacent to the body of the machine.

serai No. 632,452. (No model.)

Here the said casing consists of a plate cast ing B2, provided with a circular aperture B3. A bracket B4, in which there is formed a bearing Z9, extends from the said plate outward to the center of the said aperture. The outer side of the casing B' is provided with a bearing b opposite the bearing b. In the two bearings b and b is mounted a short hollow shaft O, the hollow interior of which cis polygonal in cross-section, preferably square. The shaft (l carries a sprocket-wheel O.

In the upper end of the elevator-casing is mounted a second short shaft D, which carries an outer sprocket-wheel D,adapted to be driven by the sprocket-chain D2 from one of the sources of power of the machine. Vithin the casing of the elevator the shaft D carries a second sprocket-wheel D3. The two sprocket-wheels C' and D3, with the sprocketchain D4 and the buckets`D5,carried thereby, constitute the elevating mechanism of the elevator B. An exit-spout E leads from the upper end of the elevator and is adapted to convey the shelled corn, when elevated, to the wagons or other receptacles provided for receiving it.

For the support of the elevator there is secured to the upper portion of the body of the machine a horizontal transverse bar F, bolted to the cylinder-casing, as at f, and extending outward on the side toward the elevator. The outer end of the said baris screw-threaded and provided with a nut f, screwed a certain distance inward thereon. A second member of the support consists of a tie-rod F', secured atone end to the frame-upright A3 and at its other end provided with an eye which is slipped onto the end of the bar F outside of the nut f. The third member of the support consists of a strut F2, the lower end of which is bolted to the transverse beam A5, hereinabove described, While the upper end is similarly provided with an ,eye adapted to be slipped on the end of the bar F. A nut f2 secures all of the three members of the support together, as is particularly shown in Fig. 2. Y

To the elevator-casing about midway of its length is secured a casting G, comprising a plate G', adapted to be attached to the said casing by bolts through the slots g and a Vbar F, while the shank of the said eyebolt extends upward through the stud G3 and is securely bolted therein. tion it will be seen that the elevator is pivoted in a vertical plane upon the support formed by the bar F, tie-rod F', and strut F3.

4vating mechanism of the elevator.

To the lower end of the elevator-casing is secured a bracket-plate I, provided with an outwardly-projecting flange I', which is slot-- ted, as at z', and thereby bolted, when the elevator is in operative position, to the transverse beam A5.

*Beneath the exit of the corn-Sheller riddle or riddles is disposed a hopper J adapted to` receive the shelled corn. In the casing J' of the said hopper is formed a bearing for one endof a shaft J3, which is provided with a helical flange J3. The said hopper is provided wi'th a circular outlet upon that side adjacent to the elevator.' The cylindrical barrel .I4-connects the said outlet with the circular aperture B3 in the adjacent side of the lower end of the elevator, the shaft J3 and fiange J3v forming in combination with the said barrel a screw conveyer. The remaini'ngY end of the shaft J3 is made polygonalA in cross-section to fit within the hollow interior c ofthe short shaft C of the elevator, although, of course, any lother form of detac'hably keying the one shaft to the other may be employed. `Thereby the conveyershaft J 3is adapted to be driven from the ele- Finally I secure to the sills A of the machine two further transverse beams K and K', which extend outwardly upon either side of the elevator and in turn support a third beam K3, whereby the three beams form a rectangular inclosuresurrounding thelower end of the elevator.-

The mode of operation ofV a corn-Sheller constructed as hereinabove described will doubtless be apparent from the said foregoing Adescription and from the drawings.

IVhen the corn-Sheller is to be set in operation, the elevator will be in its working position, as shown in full lines in Fig, l and as already described. The sprocket-chain D3 drivesv the, elevating mechanism of the eleva.-- tor, which in turn drives the screw conveyer in a manner-sufficiently obvious, therebyconveying the shelled corn from the hopper to the elevator and raising it therein to cause its exitl through the chute E.

When the machine is to beput out of'operation or transported from one place to anloosened, and the entire elevator maynowbe,

swung'upon' its pivotal mounting on thebar F., the upper end moving rearwardly and By this construcdownwardly until the whole occupies the position shown in dotted lines in Fig. 1. The elevator willnormally retain this position, resting upon the bar F and tie-rod F', and may-further be secured in such position by any appropriate means. The mounting of the elevator is with a sufficient looseness in the parts to permit of the shaft G, with the lower end of the elevator, moving slightly,

outward sufficient to disengage it from the shaft J3 of the conveyer before the elevator is tilted backward. The elevator may be thus changed from its operative to its inoperative positionand-back again without disconnecting the same from the machine and by a very slight degree of manipulation. rlhe elevating mechanism serves to transmit power from the machine tothe screw conveyer and is at the same time adapted to be readily disconnected from the one as well as from the other. Finally the framework formed by the beams K, K', andv K3 constitutes a protection to the lower end of the elevator sufficient to prevent contact between the same and the wheels of wagons which may be backed up to receive the shelled corn, and thus obviate a frequent breakage or damage ofthe parts of the elevator.

I do not consider my invention limited to the specific devices hereinabove shown and described, since many changes may be made therein, while the principles of my invention areat the same time preserved.

What I claim, therefore, and desire to secure by Letters Patent, is-
